Singh & Ahmad , sp. nov. ( Figs 1, 2 , 12, 13 ) Type material. Holotype , male. India , Arunachal Pradesh , W[est] Kameng , Bhalukpong , 21.vi.2018 , leg. Rajesh Lenka & Party (E 092035 ’26.2” N 27004 ’18.5” altitude, 168 m ) (NZCZSI, Reg. no. 7000/H10). Paratype . 1 ♂, same data as holotype (NZCZSI, Reg. no. 7001/ H10). Diagnosis. Morphologically, T. aka , sp . nov . ( Figs 1, 2 ) is similar to T. heringi Solovyev, 2014 ( Fig. 3 ) but is recognizable by the lighter hindwings. In male genitalia, T. aka , sp . nov . ( Figs 12, 13 ) differs from T. heringi ( Fig. 14 ) by the saccular process of valva apically bifurcated and with the ventral edge having series of small teeth (whereas in T. heringi , the apex of saccular process is three-pointed and has smooth edges). Another related species, though distinct externally, is T. siniaevi Solovyev, 2014 ( Figs 4 , 15 ) distributed in Northern Myanmar . However, in T. siniaevi , the saccular process is not bifurcated bearing a distinct and curved spine at the apex of dorsal edge. Description. Forewing length 13 mm . Male ( Figs 1, 2 ): frons and vertex green, former with a basal dark brown band; labial palpus dark brown, antenna dark brown but with paler rami; thorax green dorsally; forewing green dorsally, paler ventrally, costa and cilia dark brown, submarginal series of dark brown elongated spots, a subbasal patch of brown scales on the paler region of inner area; hindwing dorsally yellowish brown, cilia dark brown, inner area with elongated patch of scattered brown scales, ventrally concolorous; pectus and legs covered with dark brown scales; abdomen yellowish brown. Male genitalia ( Figs 12, 13 ) with uncus broad, tapering apically, apex with a pointed spur; gnathos upwardly curved, gradually tapering, reaching half the length of uncus; tegumen broad; valva rhomboidal; saccular process broad, approximately rectangular and flap-like, apically bifurcated, bearing a series of small teeth on ventral edge; costal process membranous, narrowing to a rounded apex; aedeagus constricted medially, with a large, subapical process; vesica with a long row of compactly arranged small claw shaped cornuti. Female unknown. Distribution. West Kameng, Arunachal Pradesh , India . Etymology. The name of the new species is derived from a tribe called Aka living in the West Kameng district of Arunachal Pradesh , India .
